Doors
From rolling service and fire doors to high speed and knockout doors, LDS has the door to fit your needs.
High Speed
When your project calls for a high-cycle, low-maintenance, fabric traffic door that saves energy, controls noise, isolates dust and dirt, and resets easily after an impact, count on our high performance doors to meet your standards.
Knock Out
Knockout doors are a great investment for any warehouse facility. No matter what you throw at a knock out door, it'll stay on the job, eliminate down-time and cut repair costs.
Sectional
LDS's comprehensive line of sectional steel and insulated steel products encompasses one of the industry's most complete selection of panel profiles, gauges, track styles and hardware for commercial sectional door systems.
Rolling Steel
LDS's rolling service door product line ensures that your project specifications will be met with ease and style. Ideal for situations where sideroom and headroom are at a premium, our upward-coiling service doors fit openings up to 1500 sq. ft. (139,355 sq.mm) and are available with the industry's widest array of slat profiles, curtain materials and colors, offering a virtually endless array of options to satisfy both aesthetic considerations and working requirements.
Security Grilles
Security grilles provide an array of attractive solutions for a spectrum of retail, commercial and industrial applications. Our side-folding grilles boast the shortest stacking dimension of any grille available today, and feature a handsome clear anodized finish (standard) in a variety of patterns and optional colors. We also offer a complete line of upward-coiling grilles. Constructed of aluminum, stainless or galvanized steel -- with optional electric motor -- these grilles are designed for durability and easy operation. Our comprehensive line of security grilles affords both reliability and peace of mind.
Fire Doors
We offer a wide array of rolling steel doors to meet the most demanding fire safety standards, unusual opening sizes and discerning aesthetic requirements. Designed to close automatically in the event of a fire or alarmed event, our fire-rated doors are available for service door and counter applications in commercial, industrial, institutional and retail uses.
All doors comply with NFPA-80, and are listed for both masonry and non-masonry applications -- including installation to wood or steel jambs within drywall. The Fire SentinelT time-relay release mechanism provides an added measure of safety to control the doors' closure. Also available is the Fire MinutemanT Chain Reset Hoist, designed to eliminate the need to release a fire door's spring tension on fire drop mode and allows one person to reset the door from the floor.
